second

A♭–B♯ is a second, as it encompasses two staff positions (A, B), and it is doubly augmented, as it exceeds a major second (such as A–B) by two semitones. A–C♯ is a third, as it encompasses three staff positions (A, B, C), and it is major, as it spans 4 semitones.

A ninth is one more note. The octave. A second is two notes right beside each other. A ninth would have either the bottom note an octave lower, or the top note an octave higher.

Introducing the ninth note The eighth note is the same as the root note, but one octave above. The ninth note is the same as the second note, but one octave above.

Second. And the thing about the major second is of course that's another way of just saying a tone. It's the note above. It is a really small step in pitch the smallest that we've looked at so far

At 120 BPM (beats per minute), which is a typical pop song tempo, every beat lasts half a second. Divide 60 by the BPM to get the length of a beat at other tempos. You can use the Google metronome to try out tempos expressed in BPM.

What Are First and Second Endings? Sometimes a repeated section has two different endings. The first time through you play the first ending and the second time through you play the second ending. This happens a lot in music and there is a common way of notating it.

The second degree is octave equivalent to the ninth. The ninth chord could be alternatively notated as seventh added second chord (C7add2), from where omitting the 3rd produces the seventh suspended second chord (C7sus2). An added ninth chord is a major triad with an added ninth – Cadd9 consists of C, E, G and D.

If you have the 3rd and the 7th in the chord already and also have a 9, you'll have a 9th chord. If you have the 3rd, but you do not have the 7th, then you have an “add 9”, as you have just added the 9th to the triad. 2nds come in when the 3rd is missing, but have the 2.

In lead-sheet notation, adding “9” to a chord symbol means the 7th is also present. “9” is “2” an octave higher and always comes from the major scale unless otherwise specified.

major second (plural major seconds) (music) an interval that is equivalent to two half steps. The major second has a pitch ratio close to 9:8.

The Major 2nd is often called a Tone or Whole Step, two fret step on the guitar neck (2 semitones).

The pulse is measured in BPM (beats-per-minute). A tempo marking of 60 BPM equals one beat per second, while 120 BPM equals two beats per second. A metronome is commonly used as a practice tool to help maintain a steady tempo while learning difficult passages.
